Unfamiliar with the story? It sees elephant Horton looking after an egg for his birdy mate Maysie, protecting it through a series of mishaps including being captured by hunters and getting stuck in a circus. And when Maysie turns up again demanding the egg back, things don’t quite turn out as she expects – in a good way for Horton.

As ever with Dr. Seuss, the rhymes and wordplay are marvellous. Like Oceanhouse’s previous ‘omBooks’, this has voice narration and sound effects, as well as features designed for young children learning to read, like individual words being highlighted as they’re read, and zooming up when touched.
